Paper sheet feeder

Abstract

A paper sheet feeder (1), comprising a bill feeding means (4) having a motor (11) for feeding a bill (A) as a paper sheet along a bill feeding route (2), a bill detection sensor (15) disposed in the bill feeding route (2), and a control means for stopping the driving of the motor (11) after the bill passes the bill detection sensor (15) and positioning the bill (A) at a specified position on the downstream side of the bill detection sensor (15), wherein the control means (25) controls the driving time of the motor (11) after the bill (A) passes the bill detection sensor (15) based on a time (T1) required for the bill (A) to pass through the specified interval of the bill feeding route (2) positioned on the upstream side of the bill detection sensor (15).

Description

technical field [0001] The present invention relates to a paper conveying device, in particular to a paper conveying device for conveying banknotes and other papers (original text: paper leaves) installed inside automatic vending machines, currency exchange machines and game machines. In particular, it relates to a sheet conveying device for positioning sheets at predetermined positions. Background technique [0002] Generally, each machine body of an automatic vending machine, exchange machine, game machine, etc. is equipped with a banknote conveying device, which conveys the banknote inserted from the banknote insertion port along the banknote conveying route, and at the same time recognizes the banknote on the way of guiding the banknote. True and false, and the banknotes identified as genuine banknotes continue to be transported to the stack storage downstream of the banknote transport route.

Problems solved by technology

[0028] However, according to the above-mentioned conventional banknote transport device 31, the motor load is caused due to environmental changes such as the temperature of the installation place such as an automatic vending machine in which the banknote transport device 31 is installed or due to fluctuations in the motor power supply voltage of the banknote transport mechanism 4. If the banknote A changes, the conveying speed V of the banknote A will change. Therefore, after the banknote recognition sensor detects the passing of the banknote A, even if the motor is stopped after being driven by a preset pulse, there will be a delay due to the drive of the motor. When it is difficult to stop the rear end of banknote A at the specified position due to the fluctuation of inertial force

[0029] For example, when the automatic vending machine equipped with the banknote conveying device 31 is installed in a high-temperature place, or when the motor power supply voltage of the banknote conveying mechanism 4 is a high voltage (HV), the load of the motor will be smaller than that at normal temperature. The conveying speed V is fast, therefore, after the banknote detection sensor 15 detects that the banknote A passes through, even if the motor is driven by a predetermined pulse and then stopped, the inertia after the drive of the motor is stopped will be lower than that at normal temperature. Therefore, the rear end of the banknote A will be sent too much downstream of the specified position, so that the upper end of the banknote A stored in the stacker 19 cannot be blocked on the banknote back-feed prevention lever 20 and protrudes out of the banknote A. In the banknote transmission line 2, the storage operation of the banknote A delivered next time is hindered, and the problem of banknote jamming occurs

[0030] In addition, when the automatic vending machine equipped with the banknote conveying device 31 is installed in a paper temperature place, or when the motor power supply voltage of the banknote conveying mechanism 4 is low voltage (LV), the load of the motor will be larger than that at normal temperature, and the banknote A Therefore, after the banknote detection sensor 15 detects the passage of the banknote A, even if the motor is driven by a predetermined pulse and then stopped, the inertial force after the stop of the motor is higher than that at normal temperature. Time is small, so the banknotes cannot be sent to a certain position (under-feeding), and there is a problem that the banknotes A cannot be reliably stored in the stack memory 19.
